The most effective way to use mantras is by working with one at a time. Pick ONE mantra that resonates with you and try to repeat it as often as you can, out loud or silently to yourself, throughout an entire day.
A prayer and a mantra to invite loving Spirit into your day.
Listen and repeat.
My body is never asking for alcohol. When I desire alcohol it is because of a story that I carry in my MIND, and my MIND can be changed.
What I give my attention to, I give my power to. Energy goes where attention flows and I practice giving generous attention to the woner of the world around me.
I trust that Spirit is always with me and ready to guide me. I simply need to pause, turn my attention inward, get still and quiet and say,
Spirit is with me now.
